In general, the present invention comprises a spindle or other means forholding a bobbin or'the likein delivering position, a chute or runwayfor transferring the bobbin to the spindle, means for manually operatingthe spindle to dofi or eject a spent. bobbin, and

automatically-operated means to return the spindle into position toreceive a fresh bobbin and to thereafter move it into'delivering position. The invention also contemplates the use of a traveling belt or.conveyor associated with the bobbin-receiving chute to continuouslysupply bobbins in position tobe placed in the chute to transier them todelivering position.

\ The invention as herein shown is applied to use one winding machinefor winding thread, yarn and other strand material, but

the device .is also adapted for use on other typesml textile apparatusin which yarn or the like is transferred from one carrier to another invarious and sundry processes of the textile art.

Referring to Fig. l of the drawings, the

winding machine as herein shown is supported on-legs or standards 2 andcomprises a plurality of heads or units surmounting a horizontal bed orframe 3 extending between the legs. The winding mechanism as hereinillustrated by way or example comprises a drum or drive-roll 5 forrotating the cop or package which is wound on a mandrel or the end of aswinging arm 7 which is pivoted at 8 to an upright 9 on the machineframe,

' the package being thus supported with its periphery in contact withthe drive-roll 5 to adapt it to be driven therefrom as its axis recedesfrom the roll during the increase in diameter of the winding. The strandof yarn or other material, indicated at y, is traversed longitudinallyof the cop-holderfi during the rotation of the latter by means of areciprocating thread-guide 10. The thread-gu'de 10 is mounted to slideon horizontal tracks or ways 11 and 12 and connected thereto is a bowlor roller 13 which engages a helical groove 14 in the rotating cam 15wherebyto reciprocate the guide. The construction of the windingmechanism as above described is well known to those versed in thepresent art and is therefore not herein illustrated in detail.

Each unit of the winding machine is usually' vprovided with atension-device for applying resistance to the draft on the yarn as 1tfeeds to the cop or package being wound, and the present drawingsillustrate adisktension for this purpose. In Fig. 1 the tension-deviceis shown as mounted on a bracket 17 which is bolted to the front of theframe of the winding machine at 18 andprovided with a horizontal shelfor rest 19 supporting a vertical spindle 20. A pair of tension-d'sks 21are mounted on the spindle 20, and a weight-holder 22 slidable on thespindle thereabove carries a suitable number of weights 23 which applypressure to hold the tension-disks against the strand of yarn drawingtherebetween. A spring'24 is preferably interposed between theweight-holder 22 and'the upper tension-disk to provide for theseparation of the tension-disks whenknots and enlargements passtherethrough without moving t e tension-weights.

The strand of yarn y leads through an opening or guide-eye 26 at oneside of the shelf 19 and draws across the top of the shelf to feedbetween the two tension-disks 21. From the tension-disks the strand 3draws through a suitable slub-catcher 27, as usually provi ed, andthence leads to the threadguide 10 to be fed therefrom and traversedthereby onto the cop or package being wound.

In delivering am or other strand material from cops, obbins and othertypes of headless packages, the strand is usually drawn off over the endof the package and for winding machines the supplies are generallyarranged below the winding units with their axes in line with the pointto which the yarn draws as it feeds through the tension-device. In thepresent application of the invention to a winding machinethesupply-holders, one for each winding unit, are supported from ahorizontal rod 28. which extends between arms or brackets 29 attached tothe legs 2.

As shown in Fig. 1, the brackets 29 are his tened to the we of the legs2 by means of clamps 30 secured in' place by bolts 31, and the rod 28 isheld in hubs 32 at the ends of c the brackets by means of set-screws 33.

A series of inclined arms or brackets 34 are bolted to the front of theframe of the wind-' ing machine to extend outwardly above the brackets29. Thebrackets 34 serve as upper supports for the chutes and runwaysinto which the bobbins are placed and down which of the machine and isthereby continuously i i they slide to apply them to the spindles ordriven to travel it longitudinally of the trough. The traveling belt 37is provided asa means for conveying'bobbins from a source of supply intoconvenient position to be picked u .by the operator and placed in thechute w ich delivers them to the supplyholder. The bobbins may be fed tothe conveyor-belt from a suitable hopper, not shown, or by manual meansas desired.

The bobbin-chute 40 comprises a pair of wing-like sections or plates 41curved to conform to the shape of the bobbin B and supported on uprightinclined rods 42 and 43. The upper ends of the rods 42 and 43 are heldin bosses or hubs 44 projecting from an arm or bracket 45 which isattached to the trough '35 by means of a screw or screws 46 extendingthrough an overhanging flange 47 on the side of the trough. As shown inFig. 3, the rods 42 and 43 are secured in the hubs 44 by means ofset-screws 48 and the plates or wings 41 have hubs 49 surrounding therods and fastened thereto by means of set-screws 50, see Fi 7. Theplates 41 are thus rigidly attac ed to the rods at their upper endswhile their lower ends have ears or projections 51 bearing against thesides of the rods to hold them in position thereon. The sides of thechute 40, comprising the wings or plates 41, are flared outwardly at thetop to facilitate the insertion of the bobbins thereinto and as eachbobbin slides through the chute it is guided by the two rods 42 and 43in the manner as later more fully explained. It will be noted byreference to Fig. 7 that the roddesignated 42 is of hollow or tubularcon-j struction whereby to adapt it to receive ahorizontal rod 28,before referred to. The

bracket 53 has ahub 54 encircling the rod 28 the hub 54 are two arms 56formed with bosses at their ends bored to receive the rods 42 and 43whichare secured fast therein by means of set-screws 57, see Fig. 5.

The plunger-rod extends downwardly through the hollow rod .42 and isbent at its lower end to form a right-angled arm 61 which projectsoutwardly between two lugs 62 on the under side of one of the arms 56and then extends laterally in the direction of the rod 28. The two lugs62 prevent the rod 60 from turning within the hollow rod 42 and the arm61 provides means for operating the control-mechanism of thebobbin-spindle in the manner as later explained. Secured to the upperend of the plunger-rod 60' is a finger piece or push-button 65, beneathwhich is a elical spring 66 coiled around the rod. The spring 66 bearsagainst a washer 64 arranged above the boss 44 in which the hollow rod42 is held and serves as a means for normallyholding the plunger-rod inraised position, as shown in Fig. 1, with its arm 61 hearing against'thebottom of the bracket 53.

The bracket 53 serves as a supportfifor a bearing-member 67 whichcarries a pivot for rockably mounting the bobbin-spindle As shown mostclearly in Figs. 4, 5 and 6, the bracket 53 is provided on one side witha rectangular portion 71, to which is bolted the member 67. The member67 is formed with a longitudinal slot 68 through which extends a bolt 72screwed into the bearing 71. The purposeof. the slot 68 is to providefor lateral adjustment of the member 67 which supports the spindle sothat the latter may be set at different distances from the rods 42 and43 in accordance with the diameter of the bobbins being used assupplies; it being understood that the bobbins slide down the runwayformed by the rods 42 and 43 to impale them on the spindle 70.

On the bottom of the member 67 is a hub 73 which receives the reducedend of a pivotstud 75 held in'place in the hub by a set-screw '7 6, seeFig. 5. Pivoted to turn on the headed end of the stud 75 is a disk-likemember 77 formed on its periphery with a socketed hearing 78 in whichthe end of the spindle 7 0 is stepped and held in place by means of asetscrew 79. The disk 77 is provided with a radial arm 80 formed with aweight 81 at its end which acts to rotate the disk on its pivot to movethe spindle 70 from normal delivering position, shown in Fig. 1, downinto inclined position as illustrated in Fig. 2, whereby to eject thespent bobbin-tube or yarn carrier 6 03 from its end. The disk orrotatable member 77is maintained with the spindle 70 in verticalposition while the bob-- bin B isdehvermg its material by means" of alatch 85 which engagesa suitable detent-shoulder 86 on the periphery ofthe disk,

see Fig. 1.

The latch 85 shown in detail in Fig. 9, is

pivoted on a pin 87 fastened in a boss at the rearward end of the member67 by means of a set-screw 88, see Fig. 6.. The latch '85 is formed witha weighted arm 89' projecting rearwardly from its hub and is providedwith a forwardly and upwardly curved arm 90 which terminates in a fork91, shown most clearly in Fig. 4. The fork 91 straddles the sides of thespindle 70 when the latter is either in vertical or slightly inclinedposition to adapt the latch 85 to be struck by the end of thebobbin-tube or carrier 5 as the latter slides down the runway and isimpaled on the spindle. @n the underside of the latch 85 is a tooth orprojection 92 which engages with the detent shoulder 86 on the peripheryof the disk 77.

The periphery of the disk 77 is formed with a second notched shoulder 93which is engaged by the toe 94 of a pawl 95 pivoted on the pin 87 onwhich the latch 85 is mounted. The pawl 95 has an arm extendingrearwardly and downwardly from its pivot which provides a weight forholding its toe-portion 94 against the periphery of the disk 7 7 Theupper forward edge 96 of the pawl 95 is adapted to be engaged by anabutment or shoulder 97 on the side ofthe latch 85, whereby when thelatter is rocked by the engagement of the bobbin 5 with its forked end91 the pawl 95 will be released from the notch 93 in the disk 77 toallow the weight 81 on the disk to turn the latter to shift the spindle.70 from the plunger-rod 60 is normally maintained in position above theweighted arm 89 of the latch 85 so that when the finger-piece orpush-button'65 is pressed to slide the rod downwardly the arm will actagainst the top of the weight to rock the forward end of the latch 85upwardly to release its detenteprojection 92 from the shoulder 86 on thedisk 7 7. As these detents are released the disk 77 will turn under theaction of its weight 81 to swing the spindle 7 0 from the position shownin Fig. 1 to dofing position illustrated in Fig. 2. The

method of operation of the complete device is 7, therefrom led upthrough the guide-eye, 26 and thence drawn through the tension. deviceto the thread-guide 10. the winding proceeds in the usual manner.The'end of the strand being attached to the cop-holder 6 thelatter islowered to place its periphery in contact with the rotating drive-roll 5and the roll will therefore frictionally drivethe 'cop-holder'to windthe 'yarn thereon with osition shown in Fig. 3 to that illustrated inltd lid

tea g weighted tail-piece or arm 89 of the latch 1 9 at such an anglethat the tube 5 will drop bobbin.

the thread-guide 10 traversing the strand back and forth to deposit itin helical coils which build up in layers to form the package. As thewinding proceeds and the yarn is taken oil from the bobbin B, eventuallythe end will run out and the operation of the machine is arrestedthrough the automatic action ofinstrumentalities as usual] provided, butnot herein shown or describe The spindle is normally maintained invertical relation to support the bobbin B in delivering position by theaction of the weight 81 which holds the disk 77 with its notch 86engaged by the detent-projection 92 on the latch 85, see Fig. 1'.

When it is observed that the yarn on the bobbin B is almost exhausted te operator assumes a station at the front of the suply-holder andimmediately the winding has een arrested the push-button or finger-piece65 ispressed downwardly to project the plunger-rod 60 through the hollowrod or tube 42. The downward sliding movement of the rod 60 carriesitsarm 61 against the 85 to rock the latter into the osition shown inFig. 2 whereby to release its detent-proection 92 from the shoulder 86.As the disk 7 is thus released from the latch 85 the weighted'arm 80will turn it on its pivot to swing the spindle 70 to the right anddownwardly into the position illustrated in Fig. 2 of the drawin It.will'be understood that as the weight 81 swings across center itsmomentum will carryit therebeyond, its motion being augmented by the.weight of the spindle 70 and the bobbintube 6 to continue the clockwiserotation of the disk 77 until the spindle is inclined off from itsend..- A suitable bobbin-box or other receptacle, not herein shown, isusually placed below the-supplv-holders to receive the emptybobbin-tubes or yarn-carriers as they are ejected therefrom.

. Now, after thedisk 77 has been turned into the position shown in Fig..2 and the bobbintube dotfed or ejected therefrom, the mo-' mentum ofthe weight 81 isfinally overcome.

and the arm 80, acting as a pendulum, swings the disk back in theopposite direction. This return movement of the weighted arm 80carriesthe disk 77 around until the toe 94 on the pawl 95 snaps intoengagement with the notch 93 in the edge of the disk. The disk 77 ,isthereby locked in the position illustrated in Fig. 3 of the drawings tohold the spindle 70 in parallel relation to the rods 42 and 43 whichform the runway for the Stated briefly, after the dofiing of the emptytube 6 the disk 77 is automatically swung back under the action of theweight 81 to aline the spindle 70 with the axis of the bobbin-chute 40.

It will be understood that immediately the detent-latch 85 has beendisengaged from the shoulder 86 on the disk 77 the finger-piece thetraveling belt or conveyor 37 and entering it through the top of thechute, releases it to permit it to slide down the runway. As the bobbinB slides down on the rods 42 and 43 the end of the bore in the tube 1),which is usually beveled orbelled outwardly as shown at m in Fig. 3,vrides over the rounded end of the spindle 7 O and is impaled'thereon.The bobbin B gains momentum as it slides down the runway and aided bythe action of gravity the end of the tube 6 strikes against the forkedend 91 of the latch 85 with some force. This impact of forked end 91downwardly with'a quick action and its lateral shoulder or abutment 97strikes against the forward end 96 of the pawl 95 to rock thelatter torelease its toe 94 from engagement with the notch 93 in the disk 77. Thedisk 77 is thereby released to be acted upon by its weighted arm 80which tends to swing it in a clockwise direction. In the meantime,however, the latch 85 has been carried down until its projection 92brings up against the periphery of the disk 77 and consequently the diskis turned only to a slight extent, or until the shoulder 86 on its edgebrings up against the projection 92 on the latch. This last turningmovement of the disk 77 carries the spindle 7O into vertical positionwhere it is held locked by the latch 85 to maintain the bobbin B erectwith its axis alined with the guide-eye 26 of-the tension-device, seeFig. 1. It will thus be apparent that after the dofiing of the emptybobbin-tube 6 through the manual operation of the push-rod 60 thebobbinholder is first turned into position to receive a fresh bobbin asit slides down the runway, and then'the action ofimpaling the bobbin onthe spindle 70 releases the disk 77 to permit the spindle to be carriedback into vertical position.

It will be observed fromv the foregoing that the invention provides abobbin-holder which is almost entirely automatic in operation, theoperator having only to press the button to effect the dofling of theempty bobbin-tube and to then place a fresh bobbin in'the chute to causeit to be impaled on the spindle and carried into delivering position.

The bobbin-chute is placed conveniently in advance of the tension-deviceof the winding wound. It will be observed by reference to. Fig. 7 thatthe side of the chute 40 is open cause it to be drawn between thetension-disks and into the slot of the slub-catcher without furtherattention on'the part of the operator.

The provision of the traveling conveyor adjacent the severalbobbin-chutes arranged supplies, the bobbins being continuously'fed intoposition at the front of the bobbinchutes so that the operator has onlyto lift them off therefrom without stooping or reaching. The inventionthus provides for a substantial saving in the time usually spent indofiing the spent bobbins and supplying fresh ones in their place, itrequiring only a few seconds to drop the bobbin into the chute and drawits end to the winding mechanism. Furthermore, the operator does nothave to bend over to lift the bobbin-tube off from its spindle andthereafter place a fresh bobbin thereon, and thus less effort and energyis used and the operators strength conserved for other duties.

Recently there has been a notable trend 1n the winding art to greatlyincrease the speed of operation of the winding machines and, obviously,when the machines are stopped for replenishing the supplies the loss' ofproduction is correspondingly greater. Conse uent- 1y, a saving in thetime required for ofling spent supplies and placing new bobbins indelivering position is reflected in a proportionate increase intheproductiveness of the machine. The present invention thereforeprovides an important improvement in the art as economizing in time andlabor and 1ncreasing the productive capacity of the machine.
